“…The floods of 2002 and 2013 caused vast damage in the region. These events prompted the International Commission for the Protection of the Elbe River, or ICPER, to rethink its flood protection strategy; the commission specifically noted in its Action Plan that the "removal of floodplain" in the past was a mistake [46,47]. The actions taken henceforth in the Elbe include, among others, the restoration of former floodplain areas via dyke removal, and thus, allowing the presence of a full-functioning, unrestricted, and active floodplain [47].…”

Compared to technical infrastructure, nature-based solutions (NBS) strive to work with nature and to move beyond business-as-usual practices. Despite decades of research from various academia fields and a commencing mainstreaming of the term, a lack of cohesiveness and pertinent methods regarding the subject matter hinders further implementation. Using a functional landscape approach, this paper aims to identify the spatial extent of existing and potential NBS locations and applies it across a case study in Germany. Inspired by hydrological models, which work with delineated hydrological response units, this research instead defines hydromorphological landscape units (HLU) based on biophysical spatial criteria to identify the potential areas that could function as NBS. This approach was tested for floodplain-based NBS. The identified HLU were then compared with historical floodplain and land-use data to differentiate between active or potential NBS. The spatial delineation identified 3.6 million hectares of already active floodplains areas, for which we recommend continued or modified protection measures, and 0.4 million ha where the hydromorphological conditions are apt to support floodplains, yet are cut-off from the flooding regime and require rehabilitation measures. The identification of NBS through explicitly defined HLU serves as a spatial approach to support NBS implementation. Taken together, our research can provide an essential contribution to systemize the emerging scholarship on NBS in river landscapes and to help in selecting and planning appropriate NBS in practice.

Research Summary By using data on provisional employees with and without criminal records, we find that existing standards of a “reasonable amount of [arrest] risk” (derived from “time to redemption” research) for an employer to incur in hiring individuals with criminal histories prove too onerous for many employees without records to meet, let alone those with records. We then propose an alternative method of assessing arrest risk across these populations—benchmarking—and provide several alternative standards, illustrating that they (a) clear a demonstrable majority of employees without records and a sizable minority of those with a criminal history and (b) do not increase the risk incurred by employers over and above the level they already accept among employees without records. Policy Implications Our findings suggest that the almost singular importance placed on “time since last” policies when conducting criminal background checks is ill‐placed as the risk of arrest across populations of employees with and without criminal histories overlaps more than the results of extant research would imply. Although future research needs to be conducted to ascertain whether our findings generalize to other employment contexts, current background check practices would be better served if they were to adopt an approach that chooses a specific threshold for comparison, which should align with an easily communicated and face‐valid cost function. Furthermore, the selected standard should (a) hold all individuals to the same standard and (b) be one that a demonstrable majority of individuals without criminal records can meet.

“…This approach strives to balance the effects of river flooding and combines it with risk management, resulting in a diversification of flood management practices that go beyond traditional measures. These practices include giving more space for rivers, re-naturalization of floodplains, and a set of improved information systems, including improved flood forecasting services, promotion of flood risk awareness and self-help capabilities (Grabs, 2016).…”

The risk of flooding in cities near riverbeds is a latent concern, especially during the rainy season. A specific case is that of Misantla, located in the State of Veracruz-Mexico, where floods have already caused social and economic damages. For flood prevention, this study proposes a digital methodology based on specialized ArcGIS, HEC-RAS and HEC-GeoRAS software, taking as a case study the urban areas located in mountainous zones of Misantla, Veracruz; likewise, hydrodynamic models supported by field studies and the use of geographic information systems (GIS) were used to know the vulnerable areas. The simulation shows the probable flood zones and the maximum depth levels that flows can reach in extraordinary rainfall events, which is an important element for risk assessment. By forecasting flooding areas, the spatial resolutions used also have a direct impact on mitigating damages caused by flooding. The study results in a risk map showing the sectors of the population most vulnerable to the problem of flooding and information for the design of protection works. In the city of Misantla, the case of this study, the simulated risk map shows that 57.3% of the surface area of the city, particularly the downtown area, is at risk of flooding.
